Usiquímica was opened on May 8, 1943 by Manoel Gimenez Henriques, an entrepreneur of Spanish origin who envisioned the potential for development of the chemical industry in Brazil. Initially named “Indústria Química Gimenez”, the company began producing Concentrated Nitric Acid, in the city of São Paulo, to meet demand in the Southeast region. With intense work and commitment to the quality of its products, Usiquímica has become the main manufacturer of Ammonium Hydroxide in Brazil and a leader in the distribution of Hydrochloric Acid, Anhydrous Ammonia, Sodium Hypochlorite, Nitric Acid and Fluoric Acid. Furthermore, it is one of the main players in the Arla 32 market.
